To all 'whom it may camera Be it known that LWARBEN S. BELLows, a citizen of the United States, residing at the city of Woreester, in the county of Worcester and Commonwealth of Massachusetts, have invented certain new and` useful {pushed dxown.` below said groove, and the 'split Washer pi'essed into place. The headthat class of'` Improvements in Brace -Socket lVrenches, of which the following is a specification.

This invention relates to wrenches wherein a bolt-recei'ving socket is provided with a brace for` the purpose of' enabling the bolts to be screwed in place more rapidly than can be done with the usual type of wrenches; and my improvements pertain to the details of construction hereinafter set forth.

Referring to the drawings forming part of this specification, Figure 1 is a side view of a brace socket wrench made in accordance with my invention. Fig. 2 is a sectional view of the head thereof. Fig. 3 is a sect-ional view of a modified form of the head. Fig. 4 is a se'ctional view on a larger Scale of the grip. Fig. 5 is a detail view of the .part of the brace where the grip is placed' Fig 6 is a cross section of, said grip. Fig. 7 is a sectional view on a larger scale of one of the grip-confining ferrules. Fig. 8 is a sectional view on the same scale of a part of the grip. Fig. 9 is a longitudinal section on a larger sea-le of the socket. Fig. 10 is an end view of the same. Fig. 11 is aside view of the part of the brace which is to be fixed in said socket. Fig. 12 is an end view of said art. Fig. 13 is a cross section of the head? Fig. 14 is a detail view showing the groove for receiving the split washer.

The main body of the brace consists of a steel rod 1 bent into the usual form shown in Fig. 1, the'terminal portion 1' of which is adapted to be rotatably secured within.

the head 2. The latter is preferably composed of sheet metal stamped into the two cup-shaped sections 3 and l4, the upper section 3 being formed with a central recess 5 entered by the extremity of the rod 1, a steel ball 6 being preferably p between, as shown in Fig. 2; the end of the part 1' being recessed to receive said ball. The lower head-section 4 is formed with an elongated opening 7 loosely fitting the bracepart 1' and a cylindrical raceway 8 for the ball bearings 9. Immediately above said balls is a solid washer 10; and above the lat' ter, a split washen 1-1 thrust into the annular groove 12 (see Figs. 13 and 14). In putting this head in place, the brace part 1' is first run. up through the lower head section .14 until.. the groove 12 is above the raceway 8; then the bals are put in, the solid Was'her section 4 is now drawn upward to present the washers below the upper part of the raceway and thereby lock the split washer in place; the ball 6 is placed in its recess, and the head-section 3 is strongly pressed into engagement with the section 4, the fit being sufficiently tight to insure the permanent fastening of the sections together. There being almost no tool-work, this head is quite inexpensivc to manufacture, while its ball bearings cause it to be well fitted for its task. w

In the construction of head shown in Fig. 3, the same is of Wood 14 bored and reamed out to receive the brace-part 1' and the wide vwooden washer 15.' The latter and a split washer 11 having been put in place upon said part, the head is placed thereon as shown; suitable glue or cement having been applied to the surfaces of said wooden members. The grip 16 consists preferably of t-Wo sheet metal sections brought together on a longitudinal plane, with their terminal edges seated in the annular grooves 17 (see Figs. 4 and 5) of the part 1 of the rod 1. Ferrules 20 having been slipped along the brace and forced upon the ends of the split grip 16 until the detents 21 of the grip engage the recesses 22 of the ferrules. The grip is now held securely in place, being kept from end play by.the grooves 17, while permitted easyfrotation thereon. The grip may, of course, be split along one line alone and bent into place about the braee, but I prefer to make the same in two separate parts. The socket 25 is a casting or forging, having a hole through it, the large end of which is made to fit the size and shape of nut for which the wrench is intended. Said end 26 is shown in Figs. 9 and 10. The upper end of said hole is cylindrical to fit the rod 1, as at 27, while the remainder 29 of said hole is fiat to fit the correspondingly shaped section 30 of said rod, as shown in vFigs. 11 and 12. The length of the rodso'that the end of said section can be upset and thereby fas'tened in the socket-castmg. Thus made, this brace socket Wrench is very inexpensive, while at the same time it is durable and eflicient in use.

What I claim as my invention and for which I desire Letters Patent is as follows, to wit;- w

1. The combination With a round rod having two annular grooves therein, of a grip comprising two shelis each ha-vin a semicircular cross section and adapte to have their ends seat loosely in said grooves, and

w ferrules loosely fitting said rod and inclosing said ends, and adapted to be fastened to the latter.

2. The combination with a round rod having two annular grooves therein, of a grip comprising two shells each havin a semicircular cross-section' and adapte to have their ends seat loosely in said grooves, and ferrules Ioosely fitting said rod and vinclosing'. said ends, each of said ferrules having recessesrwithin it, and said shells having projections adapted to engage said recesses and retain the ferrules in place thereon.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 17th day of August., 1910.,
